    Abstract: Communication devices and systems are disclosed. In one example, a communication device is configured to communicate with a communication partner device in accordance with a protocol including a first operation and a second operation. The first operation includes identification information of the communication partner device, write-instructing information, identification information of a first storage unit of the communication partner device, and data to be written in the first storage unit. The second operation follows the first operation and includes identification information of the communication partner device, write-instructing information, identification information of a second storage unit of the communication partner device, information indicating a number of the protocols, and a cyclic redundancy check (CRC) code used to detect an error in the protocol. The second storage unit is configured to store the CRC code and the information indicating the number of the protocols.

    Abstract: [Problem to be Solved] To provide a communication device and a communication system that each enable transmission of a command and data of I3C in a protocol different from the I3C.
    [Solution] A communication device according to a first aspect of the present disclosure includes: an I3C device section that generates a command and data of I3C; and a communication device section that transmits the command and data of the I3C to another communication device via a bus by using a payload in a protocol different from the I3C.

    Abstract: Communication with more reliable functional safety is disclosed. In one example, a communication device includes a packet generation unit configured to generate a packet having a packet structure in which a Mobile Industry Processor Interface (MIPI) standard is incorporated in a frame defined by Institute of Electrical and Electronics Engineers (IEEE) 1722 that is a communication standard via a network, and a timer configured to acquire a time stamp stored in a packet header of the packet. The technology can be applied to, for example, a communication system connected with an in-vehicle camera.

    Abstract: The present disclosure relates to a communication device, a communication method, and a program for offering adaptability to a wider variety of applications and enhancing reliability of communications.
    With a CCI protocol implemented as an upper layer, a physical layer transmits and receives data including an extended header and an extended footer to and from another communication device. A CCI-FS processing section compares a Desination ID included in the extended header with an ID (Source ID) given to the communication device, and determines whether or not the data is for accessing the communication device. The physical layer is MIPI A-PHY that has an asymmetrical upper layer of a point-to-point topology and is designed to allow high-speed data transmission, control data, and electric power to share one physical wire. The present technology is applicable to a communication system that is used for connection in an in-vehicle camera, for example.
